Hi,

 

I would like to know if it is possible to set up a screenshot task with NX Witness.

For exemple take a screenshot of the current video every 10 minutes and save it into a folder.

Thank You

  Hi @...,

  In the API documentation there is the following option: 

  ec2/cameraThumbnail

  If you check this in the API, you could add a wget command every 10 seconds for example by executing a script every 10 seconds with the watch command.  

  For example: 

  http://login:password@localhost:7001/ec2/cameraThumbnail?cameraId=<cameraid>&streamSelectionMode=forcedPrimary&aspectRatio=source&tolerant

  If the camera is recording continuously, you also could use the Rapid Review feature to create a time-lapse video.

  Thank You it is working well !

  Just to mention that I tried to take a screenshot for a precise timestamp. Actually the request works but the picture cannot be read.

  Here an example of the request I used for that :

  http://demo.networkoptix.com:7001/ec2/cameraThumbnail?cameraId=%3Ccameraid%3E&time=2020-01-23T01%3A00%3A00.000

   

  Timestamp format used : "YYYY-MM-DDTHH:mm:ss.zzz"

  Thank You!
